The Louis Poulsen VL45 Radiohus lamp was designed by Vilhelm Lauritzen. Vilhelm designed the Radiohus lamp in the 1940s in collaboration with Louis Poulsen for the Radiohuset building (Danish Radio House) in Copenhagen. The lamp was brought back into production in 2016 and the pendant still has the original design, brass suspension and a shade made of three-layer mouth-blown glass. The inner and outer layers are made of clear polished glass, and the middle layer is white glass. In 2019, two size options were supplemented with a smaller size, which opened up even wider possibilities for use and grouping.
